Interpreting Thyroid Uptake Scan Results
Hyperthyroidism: There are no food that reverse hyperthyroidism or make it worse.
The patient ingests radioactive iodine or has intravenous injection of radiotracer technetium to define structure, size, and function of thyroid gland. Overactive (hyperthyroid) normal, and underactive thyroid glands are determined. Sometimes autoimmune conditions and tumors of the gland can be suspected. Correlative imaging ultrasound, mr imaging, and blood tests ...Read more
I'm in the process of taking a radioactive iodine pill for a 1-123 thyroid uptake scan, will smoking pot affect the results?
No: No effect on result of the scan.See 4 more doctor answers
I just got results from a thyroid uptake scan it says they found a toxic uninodular goiter and unspecified goiter I also have itp is there a connection and what exactly is a toxic uninodular goiter also my thyroid is enlarge
Get thyroid labs: You most likely already have your thyroid levels checked. If not, you need to get thyroid labs drawn. From the uptake and scan above, your TSH should be low, which indicates hyperthyroidism. The treatment is 1)antithyroid drug, 2)i-131 ablation, 3)surgery. With itp, maybe hold off on surgery for now. Please discuss all of this with your doctor. Good luck.See 2 more doctor answers
Depends on agent: If using radioiodine, typically the tracer is given on day 1, then an uptake obtained at 4 and 24 hours later. If using pertechnetate, the uptake is done on the same day, and the scan and uptake together take about an hour or so.See 3 more doctor answers
MAY BE NORMAL: Normal range of thyroid uptake varies from lab to lab and geographic region to region. For those labs who accepts 10% to 30% as normal range, the 13.8% may be considered normal but lower range of normal.See 2 more doctor answers

I've done a thyroid u/s. Dr. Called and said they found 2 thyroid nodules. Now I'm going for a thyroid uptake scan. What will this test do or show?
Hot or cold: Thyroid nuclear scan usually with iodine 123 will show whether nodule is active (hot, increased uptake, or nonactive (cold, decreased uptake).More cold nodules are cancer.For patients presenting with thyroid nodules greater than 1 cm. In diameter (up to 20% will be malignant). They should be carefully evaluated, and managed. If greater than 1 cm. Should be closely followed or biopsied.See 2 more doctor answers
My thyroid uptake scan showed a cold nodule but TSH is normal. Will it need to be removed? It's taking long to see an endo and lab rec''s fna.
Depends: Next step would usually be a thyroid ultrasound and fna. If the, "nodule" is a simple cyst (colloid cyst) then it will likely be aspirated, if a solid nodule it would be biopsied. Most of the time a solid nodule will be negative for malignancy. If positive for malignancy, surgical removal would be the norm.See 1 more doctor answer
If I don't have graves' disease and my thyroid uptake scan is as follows: range-5% to 30% my readings- 64%, 70%, 65%. What is my best course?
Hyperactive thyroid: Thyroid uptake in range of 64% to 70% usually means overactive thyroid. Graves disease or hyperthyroidism is one cause. An overactive thyroid nodule, thyroiditis, and toxic multi nodular goiter can be other causes. An adenoma of the pituitary gland can sometimes stimulate overproduction of thyroid hormone. Clinical examination, nuclear and/or ultrasound imaging, and various blood tests can help.See 2 more doctor answers
TSH is constantly suppressed. FT3 borderline high. FT4 borderline low. Tested 5 times. Thyroid uptake scan = *low 5.3% wo nodules. Please help explain.
Thyroiditis: Why are you having your thyroid tested? What are your symptoms? Start from the begining. Medicine is not about scans and numbers. TSH is suppressed by the elevated T3 (liothyronine) as feedback inhibition. I would expect normal to high uptake but it can be low in some cases of Hashimoto's thyroiditis. thyroid scan in Hashimoto's thyroiditis can mimic a wide range of thyroid disorders. Thyroid may be burning out.
Low TSH Borderline low T4 normal t3 (liothyronine). Thyroid uptake scan. Low uptake noted w\o nodules. Radiologist said HYPOTHYROIDISM?! All other possible test norm
Need follow-up: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, there is inconsistency in your results. Both TSH and T4 being low does not add up. You may need to repeat the lab tests, not necessarily the scan, in about 6 months to see what direction these results are going in.
My TSH was 1.59 and my radioactive thyroid uptake was 20.3% at 6 hours and 42.7% at 24 hours. Still waiting on the scan results. Is this normal?
I did thyroid uptake test. My results came back as 96.4 percent function of thyroid. What should I know about this?
More info needed: The thyroid uptake test is done to diagnose thyroid problems, particularly thyroid hyper function (hyperthyroidism). You need to ask physician who ordered the test and ask to interpret your results. Previous thyroid blood test results are important to answer your question.
How safe is I 123 thyroid uptake and scan test as far as the amount of radiation you are getting during, after the test?
Very safe: The amount of radiation to your thyroid or body is extremely small with a test dose of i123 used for thyroid scans. However, it is a useless test in the evaluation of a thyroid nodule unless your TSH level is below normal. A thyroid nodule of 2.3 cm needs to be biopsied. The thyroid scan is unlikely to change that recommendation.
May be hyperthyroid: Normally it should be 30% or less at 24 hr see an endocrinologist to evaluate hyperthyroidism.
Thyroid scan: Iodine will not interfere with the technicium scan, however the tc99 scan does not tell you much. If a thyroid scan is needed, it should be done with radioactive iodine. This will require that you stop taking iodine supplements, which you really do not need to take anyway. See your endocrinologist.
